Fish that live in softer water utilize these minerals with very little left in the water. The harder the water is, the more of these minerals and elements there are. Therefor, when you put a soft water fish in harder water, they use what they need and there are simply more minerals left in the water. When you try to do the reverse, however, and put a hard water fish in soft water, there aren't enough minerals for it to sustain life properly and it will likely perish.
Thanks for the explanation. I have heard that fish can adapt but never understood why. This makes perfect sense!

I could, but I really have my heart set on a couple of Angels. Ideally, I'd like to have a couple Blue Rams as well, and I know they can be pretty sensitive. I'm not sure how long the pH will stay up with the sand. It did drop some (below 8.0) with a partial water change, so I would worry about pH drops if I did go the cichlid route.
